Kz550 best head gasket?

Okay so the head gasket is leaking by the number one cylinder. Where can I buy the best gaskets to fix this? I have a oem valve cover gasket and cam plugs. Should I just buy a oem NOS one off eBay for 55$? Or is it a waste buying the NOS gaskets? The base gasket is leaking a small amount too between the second and third cylinder too. Might as well do that too I guess? Idk how much more involved the base gasket is.

NOS does not necessarily mean OEM. Original Kawasaki part would be good.

I would ask in the GPZ550 forum. Those guys do some racing etc, and are always pulling motors apart. They will know, or at least they will argue about what is best.

If CoreyClough or Turboguzzi sees this, they may chime in. I think they are both members of both forums.
